The European Synchrotron, the ESRF, is an international research centre based in Grenoble, France.

Through its innovative engineering, pioneering scientific vision and a strong commitment from its 700 staff members, the ESRF is recognised as one of the top research facilities worldwide. Its particle accelerator produces intense X-ray beams that are used by thousands of scientists each year for experiments in diverse fields such as biology, medicine, environmental sciences, cultural heritage, materials science, and physics.

Supported by 21 countries, the ESRF is an equal opportunity employer and encourages diversity.

PhD topic: Microstructure dynamics in advanced steels studied with high throughput X-ray diffraction associated to machine learning This PhD project is a collaborative work between ESRF, SIMAP laboratory of Univ. Grenoble Alps, and the industrial partner ArcelorMittal. The context of this work is to develop a high throughput experimental methodology to feed data-driven alloy design and industrial process control. You will join beamline ID31's team at the ESRF. ID31 is a versatile instrument suited for fast high energy diffraction (HEXRD) measurements. The aim of the PhD project is to develop the methodology of high-throughput, time- and space-resolved in-situ HEXRD, aiming at monitoring in a combinatorial way the compositional dependence of the phase transformation dynamics in advanced steels. You will have to develop the fabrication of compositionally-graded steels from diffusion couples under controlled atmosphere, the implementation of time- and space-resolved fast diffraction experiments at the beamline (furnace adaptation and fast movement, data synchronisation), and the use of the very large sets of data obtained to feed physical models for phase transformations and/or machine learning approaches. Strategic scientific cases defined with the industrial partner include: ferrite-to-austenite transformation and cementite dissolution during heating, bainitic transformation in 3rd generation advanced high strength steels, and precipitation of carbides in bainitic and martensitic steels.
